工作原理

working principle

含尘气体由位于除尘器上部的进风口进入除尘器箱体，由上下行，由于重力与下行气流的作用首先把尘粒直接降至灰斗，细粉尘被滤筒捕集在外表面，洁净气体经滤筒过滤净化后，由滤筒中心进入清洁室，再经下出风口排出。随着过滤工况持续，聚集在滤筒表面的粉尘增多，此时脉冲控制仪按设定的脉冲周期和脉冲间隔控制电磁阀开启，喷出高压气体，吹入滤筒内腔，抖落外表积尘，落入灰斗，经卸灰口排出。

Dust containing gas enters the dust collector box from the air inlet located at the upper part of the dust collector, and from top to bottom. Due to the effect of gravity and downward airflow, the dust particles are first directly lowered into the ash hopper, and fine dust is captured on the outer surface by the filter cartridge. After the clean gas is filtered and purified by the filter cartridge, it enters the clean room from the center of the filter cartridge and is then discharged through the lower air outlet. As the filtering condition continues, the dust that accumulates on the surface of the filter cartridge increases. At this time, the pulse control instrument controls the solenoid valve to open according to the set pulse cycle and pulse interval, spraying high-pressure gas into the inner chamber of the filter cartridge, shaking off the dust on the surface, and falling into the ash hopper, which is discharged through the ash discharge port.

焊烟集中收集滤筒除尘器滤材的清洁通过由压差传感器控制的脉冲喷吹机构实现：当净化器运行一段时间以后，细微的烟尘吸附在滤材表面，使得滤材的透气性降低。压差传感器的两个探测头一个安装在原气侧、一个安装在净气侧。当压差传感器检测到的压差超过某一设定值时输出压差信号，脉冲发生器接收信号后顺序启动脉冲喷吹阀，洁净的压缩空气由阀口喷出，引射气流对滤筒进行吹扫直到压差低于另一设定值时才停止；滤材表面吸附的微尘在气流作用下被清除，落在室体下部的集尘斗中。脉冲喷吹需0.5～0.6MPa的洁净压缩空气，且运行中须保持连续且恒定不变的供气量。滤筒式过滤器与传统静电式过滤器、机械式过滤器相比有如下优点：排放浓度低，达5mg/m3,一般其他过滤器只能过滤0.5um以上粒径;而我司产品能过滤0.3um以上的粉尘。透气性好，气阻比一般过滤器低;清灰方便，全自动清灰，保证生产的连续性和高效性。粉尘收集，容器装卸便捷，与过滤漏斗的连接是密封的，不漏灰尘。

The cleaning of the filter material of the welding smoke centralized collection filter cartridge dust collector is achieved through a pulse blowing mechanism controlled by a pressure difference sensor. After the purifier runs for a period of time, fine smoke and dust adsorb on the surface of the filter material, reducing its breathability. The two detection heads of the pressure difference sensor are installed on the raw gas side and one on the clean gas side. When the pressure difference detected by the pressure difference sensor exceeds a certain set value, a pressure difference signal is output. After receiving the signal, the pulse generator sequentially starts the pulse blowing valve, and clean compressed air is sprayed out from the valve port. The injected airflow blows the filter cartridge until the pressure difference is lower than another set value before stopping; The fine dust adsorbed on the surface of the filter material is removed by the airflow and falls into the dust collection hopper at the lower part of the chamber. Pulse injection requires clean compressed air of 0.5~0.6MPa and a continuous and constant air supply during operation. Compared with traditional electrostatic and mechanical filters, cartridge filters have the following advantages: low emission concentration, up to 5mg/m3, and generally other filters can only filter particles with a diameter of more than 0.5um; And our product can filter dust above 0.3um. Good breathability, lower air resistance than ordinary filters; Convenient ash cleaning, fully automatic ash cleaning, ensuring continuous and efficient production. Dust collection, convenient container loading and unloading, and sealed connection with the filter funnel to prevent dust leakage.

焊烟集中收集滤筒除尘器过滤滤材特点

Characteristics of Filter Materials for Welding Smoke Centralized Collection Filter Cartridge Dust Remover

焊烟集中收集滤筒除尘器采用高效过滤筒作为过滤元件，该过滤筒选用的滤材不同于一般传统的滤材，其表面附有一层聚四氟乙烯薄膜。传统滤材（如棉布、棉缎、纸质及其他传统纤维素等）纤维间隙为5～60um，当烟尘通过时，烟尘中的一部分尘粒就会进入滤材内部而阻塞过滤元件；当阻塞情况逐渐恶化又不能进行有效清灰时，过滤元件的气阻便会上升，能通过的气流量也会随之下降。如果没有自动清灰，过滤效果会迅速下降，而该系列净化器采用的滤材表面附有一层聚四氟乙烯薄膜，其极小的筛孔可阻挡大部分亚微米尘粒；亚微米尘粒在滤材的表面聚集并形成可渗透的挡尘饼，大部分尘粒被阻挡在滤材外表面而不能进入滤材内部，在压缩空气的吹扫下能及时有效地被清除。该滤材具有相当高的过滤效率，较传统滤材至少提高3～5倍以上；且使用寿命较传统滤材提高2倍以上

The welding smoke centralized collection filter cartridge dust collector uses an efficient filter cartridge as the filtering element. The filter cartridge uses a different filter material from traditional filters, with a layer of polytetrafluoroethylene film attached to its surface. Traditional filter materials (such as cotton cloth, cotton satin, paper, and other traditional cellulose) have a fiber gap of 5-60um. When smoke passes through, a portion of the dust particles in the smoke will enter the filter material and block the filter element; When the blockage situation gradually deteriorates and effective ash removal cannot be carried out, the air resistance of the filtering element will increase, and the air flow rate that can pass through will also decrease. If there is no automatic dust removal, the filtering effect will rapidly decrease, and the filter material used in this series of purifiers has a layer of polytetrafluoroethylene film attached to its surface, which has extremely small sieve holes that can block most of the submicron dust particles; Submicron dust particles gather on the surface of the filter material and form permeable dust blocking cakes. Most of the dust particles are blocked on the outer surface of the filter material and cannot enter the interior of the filter material. They can be timely and effectively removed under the blowing of compressed air. This filter material has a relatively high filtration efficiency, which is at least 3-5 times higher than traditional filter materials; And the service life is more than twice that of traditional filter materials
